Write ‘1’ to enable interrupt signal from GPIO
Write ‘0’ to disable interrupt signal from GPIO
Write ‘1’ to enable interrupt signal from PWM
Write ‘0’ to disable interrupt signal from PWM
Read ‘1’ if wake-up event occurs
Write ‘1’ to clear the interrupt status
software. This event includes ‘calibration stuck’ and ‘tuning out of range’
Write ‘1’ to enable interrupt signal from calibration/tuning event
Write ‘0’ to disable interrupt signal from calibration/tuning event
Write ‘1’ to enable interrupt signal from end of calibration event
Write ‘0’ to disable interrupt signal from end of calibration event
System should access touch detection register when this interrupt is received.
Touch interrupt source needs to be enabled to activate key filter data.
Write ‘1’ to enable interrupt signal from touch event
Write ‘0’ to disable interrupt signal from touch event
Write ‘1’ to enable interrupt signal from proximity sensor
Write ‘0’ to disable interrupt signal from proximity sensor
